Folks
I am reading some NCDF files like this:
pathName="d:\p\"
List = findfile(pathName+"*.nc")
nosFiles=N_ELEMENTS(List)
data = ptrarr(nosFiles)
for i = 0, nosFiles - 1 do begin
ncid = NCDF_OPEN(list[i])
NCDF_VARGET, ncid, 0, lon
NCDF_VARGET, ncid, 1, lat
NCDF_VARGET, ncid, 2, concentration
NCDF_CLOSE, ncid ; Close the NetCDF file
*Here I need to save all of my files (in text format) in arrays with 3
columns and with name of NCDF file that I am reading (for instance:
L3b_20070716.txt, L3b_20070717 and so on)*
Endfor
In another word I need to pass my NCDF files name to text files names.
I don’t know how. Will you please help me?
Cheers,
Dave

Oh, I see what he was talking about. I usually do this with
FSC_Base_Filename like this:
outputFiles = StrArr(nosFiles)
FOR j=0,nosFiles-1 DO BEGIN
rootname = FSC_Base_Filename(list[i])
outputFiles[j] = Filepath(ROOT_DIR=outputDir, rootname + '.txt')
ENDFOR
You can find FSC_Base_Filename here.
http://www.dfanning.com/programs/fsc_base_filename.pro
You could also use the IDL routine FILE_BASENAME in this case.
rootname = File_Basename(list[i], '.nc')
I just find the features of FSC_Base_Filename more amenable to
what I am trying to do, usually.
Cheers,
David

I do this often and it is pretty easy to accomplish using STRING
operators. You can use something like this for the code above:
txt_list = STRARR(nosFiles)
FOR i = 0, nosFiles -1 DO $
txt_list[i] = STRMID(list[i], STRLEN(pathName), STRLEN(list[i]) - $
STRLEN(pathName) - 2) + 'txt'
Keep in mind, these do not have path names on them, but you can add
those in the OPENW.
Cheers,
Cameron
